When to plant raspberries? They can be planted in both spring and autumn, and harvesting also falls into two seasons.

AbstractRaspberries can be planted in spring or autumn, and sowing in March each year generally gives better results, because the gradual warming in spring helps raspberry seeds germinate. Also note that soil that is too heavy and sticky should be avoided when growing raspberries; raspberries are better suited to being grown in good-quality sandy soil.

Raspberries are generally planted in spring and autumn. The best time for spring sowing is from mid-March to late April, and in autumn from mid-October to mid-November. Different places have different optimal sowing times, so sow according to the local climate. However, most raspberry growers choose to plant raspberries in spring, because the gradual warming of temperatures in spring is more favorable for raspberry seed germination.

Points to note when growing raspberries

1. Seed selection

Choose excellent raspberry seeds. If the seeds are not chosen well in the early stage, various problems such as low yield, no fruiting and many diseases will appear later. Therefore, high-quality raspberry seeds must be selected for planting. Standards for high-quality raspberry seeds: the seeds should preferably be collected in the current year, be plump, and have been stored under scientific methods. If the seeds are high-quality seeds supplied directly by a professional raspberry plantation, then there will be no major problems in later planting.

2. Soaking to awaken the seeds

Before sowing raspberry seeds, soak the seeds in warm water for a period of time until the seed coat splits and the white kernel is exposed. At that point they can be taken out and sown.

3. Soil requirements

Raspberry is a light-loving plant and tolerates acidic soil. It is suitable for growing in areas with sufficient light. Slightly acidic or neutral soil, and loose, well-drained sandy loam, are also suitable for raspberry growth.

4. Sowing method

Raspberries are generally sown by broadcasting. After broadcasting, cover with about 2cm of soil, then water thoroughly in one go, and finally cover with straw mats.

5. Tending and care

After raspberry seeds are sown, watering should be carried out. When watering, make sure the water soaks through thoroughly in one go. After the raspberry seedlings emerge, remove the straw mats. During the tending process, weeds and pests should also be removed promptly, and an appropriate amount of fertilizer should be applied.

When are raspberries harvested

Raspberry cultivation is divided into two seasons, and their harvesting is also divided into two seasons. There are two types: summer-fruiting and autumn-fruiting, namely single-crop raspberries and double-crop raspberries. Summer-fruiting raspberries bear little fruit in the second year, and reach stable production in the third year. Autumn-fruiting raspberries can reach stable production in the second year. The raspberry harvest period is relatively short. Generally, harvesting from early June to mid-July is basically over, and the fruit-picking period lasts only about one month.

Raspberry growing costs and profits

Raspberries are less affected by factors such as variety renewal and market demand, and the entire raspberry growing and production cycle can reach about 20 years, making it a long-term planting project. If 10 years is taken as one production cycle, and the yield per mu is calculated at 2000 jin to work out raspberry returns, assuming market selling prices do not change much, then the longer the production cycle, the higher the returns.

1. Summer-fruiting raspberries: calculated at 4 yuan/jin, the output value per mu can reach about 8000 yuan. Excluding costs of about 5000 yuan per mu, the net profit per mu can reach about 3000 yuan.

2. Autumn-fruiting raspberries: calculated at 5 yuan/jin, the output value per mu can reach about 10000 yuan. Excluding costs of about 5000 yuan per mu, the net profit per mu can reach about 5000 yuan.
